Teachers must realize the fact that communication with ADHD children is different than with their non-disabled peers.
Children with ADHD communicate freely in small groups (2-3 children). Children with ADHD in small groups feel free to express their feelings and also develop the skill of reflective listening (i.e. you can ask questions regarding what other children have said).
When you are communicating with ADHD children, speak slowly, politely and in short sentences. Repeat the phrases if necessary and do not get irritated. To communicate effectively assign front seats near your desk to children with ADHD so that they can hear your learning instructions.
Use a ping-pong communicating technique for children with ADHD. In this technique explain to the child that when you talk, he/she will listen and when he/she talks, you will listen.
Thus, communication skills can be developed in children with ADHD by practice and spending time with them and allowing lots of time for practicing their newly developed communication skills.
